here are four sketches of substances. each sketch is drawn as if a sample of the substance were under a microscope so powerful that individual atoms could be seen. decide whether each sketch shows a sample of an element, a compound, or a mixture.

here are four sketches of substances. each sketch is drawn as if a sample of the substance were under a microscope so powerful that individual atoms could be seen. decide whether each sketch shows a sample of an element, a compound, or a mixture.

Answer

Explanation:

Step1: Recall definitions

An element has only one - type of atom, a compound has two or more types of atoms chemically bonded, and a mixture has two or more substances (either elements or compounds) physically mixed.

Step2: Analyze Substance X

There are two distinct types of particles (red - red and blue - blue), so it is a mixture.

Step3: Analyze Substance Y

All particles are the same (red - blue combinations), so it is a compound.

Step4: Analyze Substance Z

There are two types of particles (blue - blue and red - blue), so it is a mixture.

Step5: Analyze Substance T

All particles are the same (blue - blue), so it is an element.

Answer:

Substance X: mixture Substance Y: compound Substance Z: mixture Substance T: element
